BMS JB4 911TS Dyno Testing
Payam was able to trek down to Weistec today to use their all wheel drive dynojet for a little tuning on our 2014 911 Turbo S development car.
Mods are the BMS intake, BMS chargepipe, Exhaust, BMS CPI, and of course the JB4 for tuning. The ECU on this vehicle is 100% factory and never been reflashed.
Baseline testing was done on 91 octane with CPI disabled, and then Payam cranked it up by adding in some E40 fuel and turning on CPI. Frankly we're not sure what others are getting with the car but we've been pretty impressed with its performance for such mild mods. It ran 166mph at the last Shift Sector standing 1/2 mile.

Very impressive for the minimal mods on a 992.1
A 991.2 should show even higher incremental gains with the larger turbos.
Well done.

Is 477 awhp an average for 991.1 Turbo S's? Math says that is 561 HP with a 15% drive train loss. Most newer cars aren't that bad though - and are closer to 12%. Using the same math for your torque baseline and it is stating you make 616 lb ft.

Limitations of how we're doing the tuning. E40 is about as much as we'll want to run this way without reflashing the ECU and it happens to provide all the knock suppression we need at this power level.

We'll be getting the same data with the 991.2 Turbo S very soon, stay tuned! Pun intended

We have hit 850whp on our F10 M5 running x4 950cc CPI on full e85. Those cars use the same brushless LPFP system.
Once I get the larger turbos on I'll be able to push the system more and get more results. I think we can do 800whp

We haven't tried any higher concentration than full e85. I don't see anymore benefits either for going higher.

If you go higher whp numbers will stock ecu still fine are standalone a must?

We will have a couple different options depending on power goals. Dual 550cc or 950cc deatschwerks injectors. This will provide much better control and proper fuel distribution.
With the JB4 you're able to change how much fuel you want added with the CPI, and also lots of safety systems implemented.
For ex: If a ground wire got loose from one of the CPI and you did a pull, the JB4 will automatically switch into map 0 (Stock car/boost profile).
If high pressure fuel pump values are too low, or AFR gets too lean, it will switch into map 0. This implementation has saved lots of my motors when I'm doing testing in various platforms.
This is basically for people who do not want to use methanol anymore. This offers much better control as we're not using a traditional methanol nozzles.
Better safety systems, and much more practical. No more need for a meth tank, run lines from under or in the car, check for leaks, refill the tank etc.
A flash is not needed with our JB4 system.

Thanks man! Correct, this car has never been flashed. Stock ECU with just the bolts and JB4 controlling the rest. The safety systems that are implemented in the JB4 are priceless IMO.
CPI stands for Chargepipe Port Injection. We have made fittings, adapters, and lines so it will be full PNP. No hacking, cutting, or anything. Set and forget type of deal

I hope to have results and dyno numbers for the 991.2 Turbo S in a couple of weeks.
It's so much faster than my car lol

So the CPI inject meth or fuel?
